Specification of Letters Patent.

Patented July 23, 1907.

Application filed April 6, 1907. Serial No. 366.803.

To all whom it may concern:

Be it known that; we, ARTHUR F. ELKINS and HENRY HUNTER, citizens of the United States. re iding at lronton. in the county of Lawrence and State of Ohio. have invented new and usefu Improvements in Safety Appliances for l\Ioving-Picture Apparatus, of which the following is a specification.

This invention relates to to improved safety appliance for moving picture apparatus. such as kinetoscopes; and it has for its object to provide a simple and effective device whereby the film shall be safe guarded against igult ing and exploding.

With these and other ends in view which will readily appear as the nature of the invention is better under stood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

in the accompanying drawings has been illustrated a simple and preferred form of the invention; it bein however. understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawing, Figure l is a perspective View showing the safety appliance in position for operation. Fig. 2 is a vertical transverse sectional view of the safety appliance.

Corresponding parts in both figures are denoted by like characters of reference.

A designates a holder which is composed of two semicylindrical members 1 and 2 that are connected along their edges, at one side. by a hinge 3; the semi-cylindrical members are provided along their opposite edges with flanges 4 and 5 adapt d to be connected by a fastcning member such as a screw 6.

The semi cylindrical members 1 and 2 cooperate to form a sleeve'or collar wherein is mounted a tank or receptacle 7 of cylindrical shape, said tank or receptacle b ing formed of clear transparent glass and provided at its ends with flanges 8 abutting upon the ends of the sleeve or holder. The upper member 2 of the latter has an aperture 9 for the passage of a ne -k 10 that extends upwardly from the tank or receptacle, said neck, which constitutes a filling aperture, being provided with a closure ll.

The lower member of the sleeve or holder has a downwiu'd extending tubular shank l2 adjustably engaging an arm 13 having at its lower end an eye '14; adjustably engaging a supporting bracket 15 upon which said arm 13 may be secured by means of a set screw 1ft An offset screw 17 serves to secure the tubular shank I adjustahly upon the arm. 11). The supporting bracket 15 may be secured in any desired position by means of a fastening member such as a bolt or screw 18.

.In practice the tank or receptacle 7 is filled with a. clear transparent liquid such as water; the holder A is then positioned intermediate the light projecting lens holder 19 and the moving film 20, so that the rays of light will be projected through the liquid contained in the tank or receptacle which will to such an extent absorb the heat rays that ignition of the film will be pr; ti ally impossi )l'e.

By the construction herein described. the holder A may be very readily adjusted to the proper position as may be rendered necessary by varying positions of the lamp or the lens holder as well as that; of the film.

The device may be readily disassembled and packed for storage or shipment; and the liquid containing tank may be readily detached from the holder for the purpose of cleaning the tank or renewing the contents thereof.

Having thus fully described the invention. what I. claim as new is:-

l. A safety appliance for moving picture apparatus com prising a tuhnla r holder. means for supporting said holder in position, and a transpareni cylindrical tank supported in the holder and provided at the ends thereof with flanges abutting upon the ends of? the holder.

:2. A safety appliance for moving picture apparatus cont prising a cylindrical holder composed of two hingedly connected members, one of said members having an aperture and thc other membcr ha ving downward projecting tubw lal' shank, in combination with an adjustably supported arm engaging the tubular shank. means for securin the latter upon the arm, and a transparent cylindrical reccptaclc fitted in the holder and having a neck projecting through the aperture in thc upper member of said holder.

2;. A safety appliance for moving picture apparatus comprising a cylindrical tubular holder composed of two hingedly connected members provided with abutting llanges along their free edges, means for securing said glass fittcd in the holder and containing a clcar transparenl' liquid. i

4. In a device of the class described. a tubular cylindrical holder having a downward projecting tubular shank provided with a set screw. a tank or receptacle of transparent glass supported in the holder and containing a clear transparent liquid, a supporting bracket. an arm having an eye engaging said bracket and provided Willi a set screw whereby it may be secured adjust'ably in msition upon said hracln said arm engaging the cylindrical shank of the holder. and a set scrcm extending through said cylindrical shank and serving to secure the lattcr adjustably upon the arm.

in testimony whereof, we aflix our signatures in pres ence of two witnesses.
